The invention provides a real-time displacement feedback system for micro devices. The system comprises a magnet, multiple Hall sensors used for detecting and outputting multiple voltage values correspondingly generated by the magnet at the positions of the Hall sensors, and a control chip used for receiving the voltage values and calculating out the real-time position information of the magnet according to the voltage values and position parameters. The invention further provides a real-time displacement feedback method for micro devices applied to the real-time displacement feedback system for micro devices. Through the real-time displacement feedback system for micro devices and the feedback method thereof provided by the invention, precise control on displacement is realized directly. The displacement information of the magnet can be output directly. Moreover, the control precision of displacement is independent of the assembly position of the magnet, demagnetization of the magnet has no influence on displacement information, and there is no need for calibration before use.
Description
【Technical field】 [0001] The invention relates to a real-time displacement feedback system and a feedback method of a micro device. 【Background technique】 [0002] With the development of electronic technology, mobile communication terminal devices such as mobile phones usually have multiple micro-devices inside, such as built-in micro-motors that generate vibrations, voice coil motors that drive camera lenses, and the like. These micro-components have movable parts inside, and the user cannot know the real-time displacement of the moving parts when the moving parts are moving, therefore, it is impossible to precisely control the displacement of the moving parts of the micro-components. [0003] Therefore, it is necessary to provide a new real-time displacement feedback system and feedback method for micro devices to solve the above problems. 【Content of invention】 [0004] The purpose of the present invention is to provide a real-time displacement feedback system and fee...
